.To atl whom, it mtl/y concern.'

Be '1t known that l, ALruoNsn .lossen LA- lfarii'rrie, dr., a citizen ot the United States,

and a resident. of Pittsburg, in the county of tlrawtord and State o'l` VKansas, have invented a certain new and useful Garfi-iandluig Ivlechainsm, of which the following is -a full, clear, and eiiact description.

'lhe principal vobjects which the present invention has in view arez'to provide means whereby loaded cars are automatically run upon an elevator cage used for/hoisting in mine or other shafts; to provide an automatic mechanism for delivering said cars to the elevator cage, and for releasing any empty cars therefrom which may have been lowered with the elevator' cage; and to pro vide a simple and etiicicnt operating means .vherebf, the functions ot the said mecha-msm are performed.

v One embodiment o't' the present invention is disclosed in the construction illustrated in I the accompanying drawings, wherein like cuaracters ot reference indicate correspond ing parts in all the views.

itignre l is a side elevation ol the lower framing of a mining shaft, showing a trestle having railway tracks and loading cars, one oit which is upon the elevator' ea e, while the other is arrested on the incline( portion of the said track, and having mounted thereon the ear handlingmechanism, constructed and arranged in conformity with the present. iuveution; Fig. 2 is a vertical section of the same, the side timbers being removed to expose the operating members of the car hantiling mechanism; Fig. 3 is a plan View of the construction shown in Fig. l; Fig. t is a horizontal section ol the Iran'iing shown in Fig. l, being slightly enlarged to show the operative relation ot' certain of the parts, the dotted iines showing the releasine posit-ion of the car delivering,` trip; and ltig. 5 is a perspective View o'ft'he releasing` trip, shown In "Fig: et.

'the present' invention is illustrated in the Idrawiugs as showing its application more from the. members which are new, l have indicated the old members by the letters of the alphabet, while 'the new members are indicated by numerals.

rihus the letters A, A, indicate the standing frame of an elevator shaft, and the letter B indicates the lower end of the aide rail mounted upon the framework ot the shaft, to guide the car in its ascent and descent.

'The nume al 6 is used to indicate a curved or inclined section, which have provided, to aid in the operation of the invented mechanism. In the drawings I have shown the section (i as curved, and it is in such form thaty I prefer to use this section; but it will be understood that l do not limit myself to the curved shape, as this section may be at an angle to the old rail B and. deliver the ear C upon the platform D in much the same manne as it is delivered by the curved section 6. l

The hoisting mechanism for the elevator cage is that employed in the usual constructions.

ihe cross head lil, tin` uprights l? and the lower framing members ti and li, together with the tic rods l, i, constitute the :training members ot the elevator cage. Antitrietion wheels 7, 7. are niounted upon the cross head ,E and the framing members G at the upper and lower cxtreme ot1 the cage; they are shown in the presenty drawings as rollers,

bearing against the side ot the guide rails -B---tl and suitably housed.

The elevator cage., when provided with the guide rollers 7, f7, and brought to the lower end of the shaft, where the curved section (3 ot' the guide rail B is located, is coinpelled' to assume the position shown in Fig. 1 of the drawings, slightly inclined from the vertical, This inclination gives a dip or in eline to the framing,l members which constitute the platform l) of the elevator cage. Upon the platform l) there are laid short track sections K, K, to receive the wheels L, ll, oll the ra r (l. 'l`he`traclts l( are disposed so as to register with the tracks M, M, on the trcstle, built. adjacent to, and extended from both sides of the standing frame A, A.. The. trestle is constructed in such manner as to cause the tracks M, M, to assume the same inclination as is assumed b y the track K on the platform D. This-inclination is sutiiin the bar i3 is extended into sedes? ciently acute to compel the cars loaded or unloaded, to run down the incline when uuirnpeded. i

, Between the rails on the platform there is mounted a spring-actuated locking bar 8.

This is construct-ed .in the baiwlike Vforinshown particularly in Fig. 2 of the draw-A ings, and has a central cut-away portion which forms shoulders 9, 9. The bar 8 is raised into normal and engaging position by a leatx spring 10. it each end the said bar is recessed to receive the holding straps 1l, ll, and beyond the same is provided with an extension l2, l2. llroni the holdingT straps l1 to the top ol the shoulder 9, 'the'upper surface of the bar 8 is inclined.V The purpose of this bar 8 is to receive and hold bot-h the axles ll' of the car C. i

The cai' C in passing' troni the upper section oit' the inclined track M on to the platfoi'ni D depresses that end ot the bar 8 which first comes in contact with the said bar, causing it to yield, pivoting` on tho strap ll disposed at the other end of the platform. rlhe axles N, N, in this manner each over-ride the forward incline of the bar 8 and are disposed as shown in Fig. 2 olf the drawings, when the forward axle strikes upon the shoulder 9 ot' vthe bar 8 sel: u p in trout ot' the said axle, ln this position, both ot 'the axles vare within the recess between the two shoulders 9, 9. lhe spring il() being uninipeded,

instant-ly forces the bar 8 into the position shown in Fig. 2, wherein the axles lil, N, are

engaged by the two shoulders l). il, and the.

car C is heid iiiiniovably upon the track li: on the platt'orin l). llliis is the position ot the car during its ascent und "iescent.A

ln passing from the upper section ot the inclined track .lvl on to the section l: on the platform, the car is released from its fixed position, which is illustrated in Fig. 2 of the drawings, the car Z being held in the said fixed position. The member for thus holding` the car is a rod .13, inoiiiited in the framework to be protruded in the path of the wheels L of the successive ca rl`he rod i3 is pivotally mounted upon a lever la at l5 'and is held in its forward position by a spring 1G so disposed to receive the thrust of the rod i3 and theieb f relieve the l impact of the moving car.

'lhe lever la is pivotally inounted at 17 upon the iframe and is hingedly connected at i8 with a second upright bar 19. At they upper end of the bar l5) there is hingedly.

connected at 20 a section 2l of the track M, the saine 'being hinged at 22 thereon. At

the forward ond ot the lever 14 it is bent tov form a foot 23 lwhich is extended into the path o the sill 24 of the traine oi' the elevator cage. The lever llt is raised to the position shown in 2 ot' the drawings, nhereL 'i oli the lpels the lever to assume the position shown in Fig. 2 ofthe drawings' whenever the sill 2li of the elevator cage is removed troni the toot 23. V

llVlien the elevator is in its lowered position as shown in Fig. l of the drawings, the sill 24 depresses the foot 23 to the lowered position, the foot 23 forming a part of the support on which the elevator rests when in its lowerinostposition. ln this position of the position shown in Fig. l, wherein the rod 13 has been Withdrawn from in frontof the wheel L and the track section 2l has been raised to prevent the succeeding car Z from advancing to the position from which the car C has just been ino'ved. The re-y ino ral of the car C is caused by the inclination of the track M. With the removal of .the bar 13 there is nothing interposed to prevent the car from rolling down the track `When the elevator, having;` received the car C starts on its ascent, the foot 23 of the lever i4 is raised by the spring` l5 until the track section 21 is level with the track M. ln this position oil' the track section 21, the ear Z which has been arrested, is now free to nieve down the track M toward the shaft. Simultaneous with the operation which places the track section 2l in level. position, the bar i3 has been placed in the raised posi tion shown in Fig. 2 oic the drawings, so that when the car Z, loe-ing released by the lowering` of the track section 2l is pcrniittedto inove to the position shown in Fig. 2 ot' the drawings, it is arrested by the bar 13.

Extended upward in the path of the axle of the cars C and Z is a lever 26, pivotally mounted at 27 on the frame of the track end at 28 with a draw rod 2d. The draw rod 29 is connected at its opposite end to an extension 30 mounted on a block pivotally mounted at 33 upon a bar 34 which is lixedly connected to the shaft of a gear 37. The extension 30 formed of metal, While the block 32 is preferably formed of wood. lllhethcr formed of metal or Wood, however, it disposed with reference tothe extension 30 'to provide a recess 3l Whicli, in actual practice, is about two inches in height.

l/Vhen the elevator is raised as shown in Fig. 2 of the drawings, the block 32 is raised to Ythe position shown upon the end of the yhar Bel. In the descent of the elevator caffe simultaneously with the rail 24 striking tlie foot 23 of the lever 14, a sill 35 makes com. tact with the block 32 and 'depresses the saine to the lowered position shown in Figa l of the drawings. ln thus depressing the block 32 and the arm 34 connected therewith, the elevator cage has caused an arm 36 to inipinge upon the extension 12 ou the bei' t3, causing it to depress the lower in- M and upon the track K of the platform D.

trestle, and hingedly connected at the lower the foot 23, the lever 14 is caused to assume n irseI scended with the elevator, from engagement with the said bar 8.' ln this position, the

' track K being inclined and registering with the`lower section of the track M also in'- 4clined, there is nothing 'to retain the car upon the track K, and the saine immediately passes from the platform D in the direction opposite that from which the cars are receivedion the platform D.

The action above described is caused by the chainof gears 37, 38 and 39, which are suitably mounted. It will be observed that. the linal gear 39 which is ixedly connected with the shaft on which the arm 36 is mounted, is somewhat smaller in diameter than the gears 37 and 38 and, therefore, rotatesproportionately faster than tliesaid gears.

In its disengaged positionI the arin 36 assumes the position shown in Fig. 2 of the drawingsnivhile the bar 34 and the block 32 assume the ,position likewise shown in the saidview. "ift/hen new the bar 34 and block 32 are depressed through the arc ot their movement., thenarin 36 is caused to travel a somewhat greater arc, and consequently l' somewhat faster than the bar 34 and block 32. This actioncauses the end 40 oit' the said arni 3G to move. more rapidly than the.'

elevator cage, and after engagement by the said end 40 with the extension 12 of the bar 8. During the remainder o't the'movenient. 'of the cai', and o't the block 32 and bar 34e, the arm 3G depressies the extension 12 until the shoulder S on -the inclined side of the bar 8 is removed from its position interposed in the path ot' the aides N, N, of the carl" The bar 8 remains in this position,

which We will call the empty car deliver` ing position, until the. succeeding and loaded car strikes the level' 26.

With the moving of the `lever 26 from the position shown in Fig. .t in the drawings, to

that shown in dotted lines in Fig. 2, the lowerend of said lever draws the draw rod l i 29 which rotates the block from under the sill 35. As the block 32 is thus moved. from engagement withthe sill 35, a heavy spring 41 lis permitted to ele-vate the arm 36 thereby raising the end 40 roni'tlie ex- -tension 12 and permitting the bar 8 to asposition shown in Figs. l and 2 ot the drawings in full lines. In this eort the spring 42 is prevented by the side of the recessl on the block 32, the side striking against the vertical side of the sill 35 ot the elevator cage frame. When the elevator has ascended, the sill 35 being removed, the spring 42 dra-Ws the extension 3() so that the block 32- is advanced to its original' position Ato receive the downcoming elevator.

The loading and unloading of ltlu\ cais n on the lat Iorni D is automatic and ac# n l complished by the mechanism thus tar described. 'lhe hoisting is manually con-A trolled, and the hoi-sting mechanism is of any approved type. It is to warn the operator of the tact that a car has been loaded upon the platform that l have provided the line 43 and bell ci'ank Llei. The bell crank di is mounted upon a bracket 45 on the side ot the standing frame A. The pull end ot the bell crank i-t. is suitably attached to the line lt3 which is guided in a` pulley Ltti mounted upon the .said standing frame A. The line 43 is suitably led to any suitable announcing device such as a bell or whistle. The bell crank 44 is extended into the path of a pin JJ set out troni the side of the car, so that whenever thecai passes on tothe track K, the pin 47 lstrikes uponA ghe vc arni of the bell crank 44, causing, throng the line 43, the signal to be given-to the hoisting operator, who then is at. liberty to raise the elevator cage, knowing the saine to be loaded. At the end of the car is fixed another pin 47, also adapted to contact with the free arm of the bell-craiik 44;, so that if occasion requires, two signals may be sounded, one bythe pin 47 and the other bythe pin 47a.

On theside of the tracks there are inount ed guard rails 4S, which are'extended from above the hinged position ofthe section v2l to below the position ot' the rod` 13. The rails 48 are mounted upon uprights 49 which are rigidly secured'to the track bed. The object ot' the rails 48l is to extend over the Wheels L, L, to prevent the saine juniping from the track M.

Having thus described my invention, I claim as newY and desire to secure by Letters Patent:
